Second-round Draft pick Greg Robinson has revealed his frustrations at having to learn a new position while studying the St Louis Rams' playbook.
Robinson is being asked to train as a guard, despite being known as one of the most promising offensive tackles in the game.
"It's frustrating that I'm not up to pace right now because the playbook is more intense and things are changing but once I get back to where I'm comfortable, things will calm down and I can be myself out there," said Robinson, according to the NFL's official website.
"I didn't know what to expect, honestly. I put a lot of pressure on myself because I like to challenge myself.
"It's something I want to do and just stand out to the coaches and let them be comfortable with their choice."
Despite learning his new position, it is thought that Robinson will return to left tackle in the coming years, where he is expected to flourish for the Rams.
